Obsolete automation parts sourcing

Siemens legacy and phase-out enquiries

For installed SIMATIC equipment, send the complete article number together with a nameplate photograph and any hardware or firmware version. Identify whether you need an exact replacement or can review an alternative.

Siemens has published phase-out information for S7-300 and ET 200M families. Family-level announcements are a starting point: the exact article number and current manufacturer status must be checked before describing a specific part as discontinued or unavailable.

Different lifecycle terms mean different things

A phase-out announcement, spare-parts phase and discontinued status should not be treated as interchangeable. Status can vary by brand and ordering code. For example, Rockwell distinguishes Active Mature, End of Life and Discontinued. We ask you to provide the exact model so the enquiry can be assessed against relevant manufacturer information.

What to include in your legacy-part request

1. Manufacturer, complete ordering code and clear label photographs.
2. Quantity and whether an exact hardware or firmware version is required.
3. Required condition: new, unused surplus or another explicitly acceptable condition. Ask for the offered condition to be documented.
4. Destination country, delivery location and target date.
5. Inspection, traceability and documentation requirements.
6. Whether an engineer-approved alternative can be considered.

Multi-brand industrial enquiries

Send enquiries for Siemens, Schneider Electric, ABB, Allen-Bradley / Rockwell Automation, Mitsubishi Electric, Omron, Yaskawa, Delta, Panasonic and Fuji Electric components. This is an enquiry scope, not a stock list or an authorized-distributor claim. Availability is reviewed for each exact part.

International procurement requirements

For enquiries from India, Southeast Asia, the Middle East, South America and Russia, include the full destination, end application, requested shipping terms and documentation needs. Supply and delivery feasibility are confirmed individually in the quotation.

Replacement decisions need technical review

A similar model name or headline rating is not sufficient to establish interchangeability. Have the responsible engineer review supply, interfaces, dimensions, firmware and machine requirements before approving a substitute.
